Free version of the Kastri library (commercial version is still coming.. it's taking longer than expected)

From Delphi Worlds:


  • Is a cross-platform library which builds upon the existing RTL and FMX libraries in Delphi
  • Supports a number of newer APIs that you won't find in FMX/RTL, and "backfills" for missing APIs
  • Is structured in a way so as to avoid creating unnecessary dependencies
  • Follows strict coding standards to ensure consistency and readability
  • Is kept as simple as practicable

You'll find demo applications in the Demos folder, including those associated with articles posted on the Delphi Worlds blog:

These will be added to and updated over time as older articles are revisited
